Art & Language, Transatlanticism and Conceptual Cosmopolitanism

open access: yesTate Papers, 2017
This essay looks at the role of transatlanticism in the early work of the conceptual art collective Art & Language, arguing that it imagined and questioned the transatlantic as a virtual place in which a cosmopolitan mode of art could be created.

Coral snake venoms: mode of action and pathophysiology of experimental envenomation

open access: yesRevista do Instituto de Medicina Tropical de São Paulo, 1987
Coral snakes, the New World Elapidae, are included in the genera Micniroides and Micrurus. The genus Mlcrurus comprises nearly all coral snake species and those which are responsible for human snake-bite accidents.

Aging in Brazil [PDF]

open access: yesThe Gerontologist, 2018
The population in Brazil is aging at a fast pace and in a context of historical socioeconomic and regional disparities. In the last decades, the country has developed important policies and legal mechanisms to guarantee older adults' right to age well and with dignity.

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

open access: yesAdvanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

open access: yesAdvanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Tag questions Tag questions

open access: yesIlha do Desterro, 2008
The so-called 'tag' structures of English have received a lot of attention in language teaching programmes, attention that is not hard to justify when one considers the problems and anxiety they can occasion for many foreign learners.

Grain Refinement During Severe Plastic Deformation and Similitude of Subgrain Formation: A Molecular Dynamics Study

open access: yesAdvanced Engineering Materials, EarlyView.
Molecular dynamics is used to investigate structure refinement during severe plastic deformation. The results show similitude with experimental data. Molecular dynamics simulations of severe plastic deformation of monocrystalline and polycrystalline samples by multiaxial compression of aluminum are carried out.

Tensión premenstrual - Clasificación y dificultades diagnósticas

open access: yesRevista Colombiana de Obstetricia y Ginecología, 1955
Continuando algunos trabajos suyos sobre tensión pre-menstrual, el autor afirma que el 90,4% de las mismas llegarán a tener hipertensión menopáusica. El mismo autor da una clasificación etiológica de la tensión pre-menstrual dividiéndola en cinco grupos

Gardiquimod Nanoemulsion Targets Cutaneous Leishmaniasis Lesions Reducing Systemic Toxicity and Parasite Burden

open access: yesAdvanced Healthcare Materials, EarlyView.
Nanoemulsion delivery of a TLR7 agonist enhances safety and promotes colocalization with Leishmania‐infected macrophages in skin lesions, enabling a ∼2‐log reduction in parasite burden. However, tissue‐level constraints and TLR‐driven regulatory feedback generate a mixed immune response that limits complete parasite clearance.

Eutectozymes as Soft Hybrid Materials for Advanced Biocatalysis

open access: yesAdvanced Materials, EarlyView.
Eutectozymes are sustainable hybrid materials that embed a GOx–HRP cascade within hydrophobic eutectogels featuring a dual supramolecular–covalent network. This architecture preserves native enzyme structure and stability, enables efficient heterogeneous biocatalysis in aqueous media, and positions eutectogels as robust platforms for next‐generation ...
